.Sh DESCRIPTION
|
|
.Nm Chown
|
|
sets the user ID and/or the group ID of the specified files.
|
|
.Pp
|
|
The options are as follows:
|
|
.Bl -tag -width Ds
|
|
.It Fl H
|
|
If the
|
|
.Fl R
|
|
option is specified, symbolic links on the command line are followed.
|
|
(Symbolic links encountered in the tree traversal are not followed).
|
|
.It Fl L
|
|
If the
|
|
.Fl R
|
|
option is specified, all symbolic links are followed.
|
|
.It Fl P
|
|
If the
|
|
.Fl R
|
|
option is specified, no symbolic links are followed.
|
|
.It Fl R
|
|
Change the user ID and/or the group ID for the file hierarchies rooted
|
|
in the files instead of just the files themselves.
|
|
.It Fl f
|
|
Don't report any failure to change file owner or group, nor modify
|
|
the exit status to reflect such failures.
|
|
.It Fl h
|
|
If the file is a symbolic link, change the user ID and/or the group ID
|
|
of the link itself rather than the file that the link points to.
|
|
.It Fl v
|
|
Cause
|
|
.Nm
|
|
to be verbose, showing files as the owner is modified.
|
|
.El
|
|
.Pp
|
|
The
|
|
.Fl H ,
|
|
.Fl L
|
|
and
|
|
.Fl P
|
|
options are ignored unless the
|
|
.Fl R
|
|
option is specified.
|
|
In addition, these options override each other and the
|
|
command's actions are determined by the last one specified.
|
|
.Pp
|
|
The
|
|
.Ar owner
|
|
and
|
|
.Ar group
|
|
operands are both optional, however, one must be specified.
|
|
If the
|
|
.Ar group
|
|
operand is specified, it must be preceded by a colon (``:'') character.
|
|
.Pp
|
|
The
|
|
.Ar owner
|
|
may be either a numeric user ID or a user name.
|
|
If a user name is also a numeric user ID, the operand is used as a
|
|
user name.
|
|
The
|
|
.Ar group
|
|
may be either a numeric group ID or a group name.
|
|
If a group name is also a numeric group ID, the operand is used as a
|
|
group name.
|
|
.Pp
|
|
The ownership of a file may only be altered by a super-user for
|
|
obvious security reasons.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
utility exits 0 on success, and >0 if an error occurs.
|
|
.Sh COMPATIBILITY
|
|
Previous versions of the
|
|
.Nm
|
|
utility used the dot (``.'') character to distinguish the group name.
|
|
This has been changed to be a colon (``:'') character so that user and
|
|
group names may contain the dot character.
|
|
.Pp
|
|
On previous versions of this system, symbolic links did not have
|
|
owners.
|
|
.Pp
|
|
The
|
|
.Fl v
|
|
option is non-standard and its use in scripts is not recommended.
